Features on page 2 Firmware Updates on page 3 Front Panel on page 4 Back Panel on page 5 Advanced Functionality on page 6 Related Documentation on page 7 "Documentation Conventions on page 8 What is the DRG200i? The Omnitronics DRG200i Digital Radio Gateway Dual Channel product is a sophisticated dual-channel digital-radio gateway with a built-in 5-port Ethernet switch. It provides the interface between one or more Omnitronics consoles such as RediTALK-Flex VoIP Dispatch Console or DX-Altus Alto Dispatch Console and two digital radios. Whether your organization is running different digital radio systems (including DMR, IDAS, and TETRA etc.) or a combination of systems, it doesn t matter! The DRG200i translates voice and data into the same proprietary digital protocol so that different radios and protocols can all connect to the one network. You are no longer restricted in your choice of protocol or need to convert your entire radio network in one swoop true interoperability is now within reach with the DRG200i. It provides organizations with a number of benefits: Phased radio network upgrades Ability to choose the protocol(s) most appropriate for the task Flexibility to interconnect multiple protocols DRG200i Product Manual 1

10 Dual-channel device is a more cost-effective solution compared to two independent digital radio gateways As the DRG200i is a dual-channel device, it can remotely control two digital radio systems over any IP network. This includes having two separate digital radio protocols on the one DRG200i. Using the DRG200i, you can: Create IP links between several digital radio systems using point-to-point or point-to-point VoIP communications. Connect a digital radio system to a VoIP radio-dispatch system such as Omnitronics Alto DX-Altus Dispatch Console or Omnitronics RediTALK VoIP Dispatch Console. Figure 1 shows an overview of how the DRG200i interfaces to external devices via its built-in Ethernet switch. Figure 1. Overview of DRG200i interface Note The number of compatible protocols is changing all the time. Please contact your local sales representative for the current list of supported digital-radio protocols.

11 Fast Ethernet ports: Integrated 10/100-BaseT Ethernet ports (x3) function as a network switch reducing the need to purchase additional network hardware. Voice activity detection (VAD): Optimizes bandwidth usage by detecting voice activity with silence suppression for bandwidth efficiency LED indicators: LEDs on the front panel make it easy to see the status. Firmware updates: Easily update the firmware via a convenient web browser interface. Voice encryption technology: Secure voice transmissions with the optional DES voice encryption with user configurable key. SIP connections: Supports incoming SIP connections from Omnitronics devices and software as well as the ability to register with a SIP server to enable SIP-telephones to access the connected digital radio system. Intuitive Configuration Interface: Makes it easy to configure the essential settings required to get two DRG products communicating or fine tune the operation by changing the advanced product features. Remote configuration: Remotely configure the DRG100 within the LAN, WAN, or Internet environment using a web browser. At the time of publication, the DRG200i supports the following digital-radio protocols (see notes below): MOTOTRBO, P25, DMR, dpmr, IDAS (NXDN), NEXEDGE (NXDN), Tetra, and PMR. The current range of radios compatible with the DRG200i is listed below: Mototrbo: DM3401*, DM3400, DM3601, and DM3600. Icom: IC-F5063* (requires extension UT126H) and IC-F6063 (requires extension UT126H). IC-FR5000 VHF repeater and IC-FR6000 UHF repeater (both support analog audio and serial data). The current list of radios compatible with the DRG200i-P25 is provided below: P25: Tait TB9100* Note Models marked with an asterisk (*) indicate the ones used during development other models are similar and expected to be compatible. This list of compatible radios is not exhaustive, and in some cases not all of the features of the radios are exposed or published by the DRG100. The fact that a radio supports GPS does not imply that the DRG200i supports it. Note The list of compatible protocols is changing all the time. Please contact your local sales representative for the current list of supported protocols. Firmware Updates The DRG200i firmware can be easily updated with a new version when it becomes available. Omnitronics periodically provides firmware updates to resolve issues or to provide additional functionality (see Updating the Firmware on page 76). DRG200i Product Manual 3

12 Front Panel The DRG200i front panel provides LED status indicators for both Channel A and Channel B, and a USB connector. Power Run LED Radio LED Ethernet LED VoIP Link USB port Status Indicators The LED status indicators are all green. The function of each LED is described below. LED LED Activity Description Power Solid green Power is supplied to the device. Run Off Blinking green (slow) Blinking green (fast) Power is not supplied to the device. LED blinks slowly when the device is starting up on this channel. LED blinks faster when this channel is operational. Radio Solid green Communications link to the radio is established on this channel. Off Communications link to the radio is not established on this channel. VoIP Link Solid green VoIP connection is established on this channel. Off VoIP connection is not established on this channel. Eth Solid green Ethernet network is connected. Blinking green Data is transmitted over the Ethernet connection. USB Port The USB connector uses a Type B receptacle. The port provides serial communications and access to the built-in Serial Monitor used for diagnostics and troubleshooting problems for both DRG200i channels (see Using the Serial Monitor on page 83). 4 Introduction

13 Back Panel The DRG200i back panel provides connectors for three Ethernet ports, power connectors, and a Reset-to-Defaults button. Power Connectors The DRG200i product is powered from +12 Volts DC connected to either the two-pin green Phoenix connector or the socket. Power connections for the Phoenix connector are indicated as follows: Ground (0V) is designated by the negative symbol (-), and Positive Supply (+12VDC) is designated by the positive symbol (+). The adjacent power receptacle is a 5.5mm socket (with 2.1mm centre pin) with +12VDC on the centre pin positive. Ethernet Ports The DRG200i is essentially a dual DRG100 with a built-in 5-port Ethernet switch: 2 internal ports connect to two separate internal DRG100 devices (designated as Channel A and Channel B); and each channel has its own IP address. 1 of the external Ethernet ports is used to connect the DRG200i to your company network (or to a DMR node) using a single Ethernet cable. The other 2 external Ethernet ports can be connected to any Ethernet device (with the proviso that the devices should not use too much of the available network bandwidth). The Ethernet connectors are located on the back panel. On each connector, the green LED indicates network connectivity is established and the yellow LED indicates activity is detected on the port. Note Do NOT connect more than one Ethernet cable between the DRG200i and the same network switch or router; otherwise this may cause problems with your IP network. DRG200i Product Manual 5

14 Reset to Defaults The Reset to Defaults button resets both channels of the DRG200i device to factory default settings. It is recessed to prevent accidental reset of the device use the end of a paper clip or some other similar object to press and hold the Reset to Defaults button while applying power (see Resetting to Factory Default Settings on page 84). Advanced Functionality The DRG200i device includes sophisticated technology to efficiently transport audio over an IP network such as the Internet or your organization s local area network. Encryption Another feature of the DRG200i is the built-in security: it supports the DES encryption standard, which can be enabled for all voice and data transmissions. Bandwidth Optimization The input audio is compressed using DSP and a codec. The compressed audio is then transported over IP. The DSP also provides Voice Activity Detection (VAD) and silence suppression. These features enable the DRG products to make optimal use of the available IP bandwidth. With VAD and silence suppression, audio packets are generated only whilst a person is actually talking. As soon as silence is detected, the transmission of data packets is suspended. VAD is also useful when connecting to communications equipment that does not provide a COS or Busy (Mute) output. VAD performs a VOX function that activates COS outputs while voice is present. Session Initiation Protocol (SIP) The DRG200i uses the Session Initiation Protocol (SIP) to dynamically connect and disconnect VoIP connections. This allows the DRG200i to be used with Omnitronics dispatch software, which can remotely connect to a DRG device to monitor or transmit audio on demand as well as control various digital radio functions. The DRG200i provides complete SIP interoperability that allows it to interact with other devices that support SIP. Third-party devices that support SIP include: Software SIP phones Allow connection from a computer to a DRG device. SIP telephone systems Allow access to radios from a phone system. SIP to PSTN Service Providers Allow access to radios from any PSTN telephone. 6 Introduction

15 Digital Radio Special Functions When paired with a digital radio and a dispatch system such as Omnitronics DX- Altus or RediTALK-Flex, the DRG200i is able to receive and transmit special functions unique to digital radios. Some of these functions include: Voice call types Initiating and accepting various voice call types with radios, such as between individuals, groups, and everyone on a digital radio network to the Omnitronics dispatch system. Radio Identification Retrieving radio IDs used by Omnitronics dispatch systems to match contacts. Emergency calls Making and receiving emergency calls between Omnitronics dispatch systems and radios. Text messaging Sending text messages between Omnitronics dispatch systems and individual or groups of radios. GPS tracking Sending radio-provided GPS coordinates to connected dispatch systems or GPS services. Special radio commands Sending special radio commands such as remote monitor or stun radio from Omnitronics dispatch systems to radios. Most of these special functions are also available on the DRG200i configuration interface for diagnostic purposes as well.

17 Getting Started This chapter provides step-by-step instructions for connecting the DRG200i to your network and to get it up and running quickly, and includes the following sections: Connecting to the Network Connecting to the Network Omnitronics offers a system configuration service at the customer s request to configure the DRG200i and other DX-Altus system components. If your DRG200i is preconfigured for your network, you can simply connect it to your network and start using it as is. In this case, you can skip ahead to the next chapter (see Basic Configuration on page 17), which explains how to use the configuration interface in case you want to make some changes to the configuration. When preconfigured, the product documentation supplied with the system will describe all of the static IP addresses used in the system including that of any DRG200i devices. However, if your DRG200i is not preconfigured, you will need to initially configure the basic network settings so that it can communicate on your network. The easiest way to configure the DRG200i is to connect it directly to your computer s Ethernet port using a network cable you do not need to use a cross-over cable. The DRG200i is factory configured with static IP addresses (see Table 1 on page 85). That is, (for Channel A) and (for Channel B). If the IPv4 address of your computer does not have a similar address (i.e., an IP address starting with x), it will not be able to communicate with the DRG200i. In this case, you will need to change the IPv4 address of your computer temporarily to the same subnet as the DRG200i. Once your computer and the DRG200i are both on the same network, the Link LED should illuminate and the Act LED should blink when network activity is detected. You can then login to the web server and use the configuration interface to configure the network settings of the DRG200i to match your network. You can then restore the network settings of your computer. The following section provides step-by-step instructions for configuring the basic network settings of the DRG200i using Windows. If you are using Mac OS or the Linux operating systems, see Mac OS X or Linux on page 16 the procedure will be similar although the steps will be different depending on the version of Linux. DRG200i Product Manual 9

18 Using the Serial Monitor to Configure the Basic Network Settings If you do not know the IP address of the DRG200i, you can use the Serial Monitor to configure the basic network settings, such as the IPv4 address, subnet mask, and gateway address to match your computer network. Once you have configured the basic network settings, you can then log in to the DRG200i and use the builtin web server to configure the other settings. Serial Monitor is primarily intended for diagnosing and resolving issues by support engineers, and is not recommended for non-technical users (see Using the Serial Monitor on page 83.) Windows This section contains information to help you get the DRG200i up and running quickly using Microsoft Windows. Although the screenshots are from Windows 8.1, the same steps also apply to Windows 7 and Windows 10. If the IP address of your computer does not have a compatible address (that is, an IP address starting with x), you will need to change the IP address of your computer temporarily before it can connect to the DRG200i by following the steps below. Note To change the IP address of your computer, you must be logged in with a user account that has administrator priviledges. Step 1: Determine the IP address of your computer You can get the address of your computer by following the procedure below.

Note If you did not change the network settings of your computer, you do not need to perform this step. Repeat Step 2: Change the IP settings of your computer on page 12 to restore the network settings of your computer back to its original settings that you recorded in Step 1: Determine the IP address of your computer on page 10. This time, however, you ll change the IPv4 address, IPv4 Subnet mask, and the IPv4 Default gateway to the original settings. Congratulations! You have now configured the DRG200i to communicate on your network, and you should now be able to connect to the DRG200i using the original network settings of your computer. Mac OS X or Linux For other operating systems, such as Mac OS or Linux, the same basic steps apply: that is, temporarily change the computer s IP address to one in the same subnet as the DRG200i, such as x, then access the DRG200i web-based configuration interface to configure the network settings of the DRG200i, and then save the configuration and restart. Then restore the network settings of your computer. 16 Getting Started

25 Basic Configuration This section discusses how to configure the basic settings to get it up and running quickly, and includes the following topics: What is the Configuration Interface? Launching the Configuration Interface on page 17 Network Discovery on page 18 Using the Configuration Interface on page 18 Viewing the System Status on page 29 Configuring the Basic Network Settings on page 32 Backing up and Restoring the Configuration on page 34 Digital Radio Configuration on page 38 VoIP/RTP Configuration on page 42 SIP Configuration on page 44 What is the Configuration Interface? The DRG200i product includes a built-in web server with a configuration interface you can access using your web browser The web pages use JavaScript so you should ensure that JavaScript is enabled in your web browser. The configuration interface consists of a series of web pages designed to help you configure and manage the operation of the DRG200i. You can access all the status information, configuration settings, and diagnostic tools in one convenient user interface. The configuration interface supports the following web browsers: Internet Explorer 9 11, Edge 38 and later Firefox 30 and later Google Chrome 14 and later Safari 5 and later It may also be compatible with other web browsers not listed above; however, Omnitronics cannot guarantee the compatibility of such browsers. Launching the Configuration Interface To launch the configuration interface, you must know the IP address of the DRG200i you want to configure so you can navigate to its web server using your web browser. If you are configuring a DRG200i with factory default settings, you can use the default IP address and type or into the address bar of your web browser. This will load the login page in your web browser. DRG200i Product Manual 17

26 If you do not know the IPv4 address of your DRG200i, you may be able to use the Network Discovery feature of Microsoft Windows to discover the DRG200i on your network, as discussed in the following section. Otherwise, you will need to refer to the information in Connecting to the Network on page 9. Network Discovery If the DRG200i and your computer are connected to the network, and UPnP (universal plug-n-play) is enabled in the DRG200i, you should be able to discover the DRG200i on your network. You will see all of the computers and devices that are currently part of the network in the Network folder or under My Network Places depending on the version of Windows operating system running on your computer. Figure 2 shows how the Network folder might appear under Windows 7. This will be similar for Windows 8.1 and Windows 10. The DRG200i product should appear with a VoIP Device name (e.g. VoIP Device DRG200i-DMR-AIS: Version ). Once you have located the DRG200i device you want to configure, double-click on it to automatically launch the login page in your web browser. Figure 2. Using Network Discovery with Windows 7 Note To discover the DRG200i on your network, the network settings of the DRG200i must be on the same subnet as the computer you want to use to access it. That is, the IP address of the DRG200i must be on the same subnet as the IP address of the computer. Using the Configuration Interface All configuration and management of the DRG200i is done using the built-in web server, known as the configuration interface. You must login to the configuration interface with a user name and a password before you can view or change any of the configuration settings. 18 Basic Configuration

27 To login, you must be able to navigate to the DRG200i on the network using your web browser, and you need to know the IP address of the DRG200i. If you are configuring the DRG200i for first time, you can use the default IP address of (Channel A) or (for Chanel B). Otherwise, you might be able to use the Network Discovery feature of Windows to discover the DRG200i on your network (see Network Discovery on page 18. The following sections discuss how to login and use the configuration interface to configure the DRG200i. Layout of the Configuration Interface Figure 3 shows the layout of the configuration interface when logged in under the administrator account the page shown here is the Network Configuration page (see Configuring the Basic Network Settings on page 32) that is displayed when you select the Network menu in Basic Mode (advanced mode provides more settings). Navigation panel Navigates the basic and advanced menus Settings area Shows the configuration settings Status area Shows the configuration status Figure 3. Using the configuration interface Along the lower-edge of this page is the Configuration Status area, which shows the status of the configuration and whether you have made any changes to the settings. This area appears on all pages with configuration settings that you can change. In this example, the configuration is unchanged (see Configuration Status on page 24). Note If you are using a version of a web browser that is not supported, the Configuration Status buttons may not be visible along the lower edge of the browser. This may happen with some older browsers, in which case, you can scroll to the bottom of the page to view the buttons. DRG200i Product Manual 19

28 The navigation panel on the left-hand side provides a basic and an advanced menu system the items shown in the menu depend on the user account you used when you logged in and which menu mode you are using (the menu modes are discussed below). When you log in, the Basic Menu mode is shown by default. The various configuration pages are accessed by selecting menu items: selecting a menu item displays the corresponding configuration page on the right-hand panel of the interface. The configuration interface has two modes of operation: Basic Mode provides access to basic configuration settings that allow you to configure the DRG200i device with minimal settings to get it up and running quickly. This mode is most suitable for simple or straight-forward installations in which the basic settings are sufficient. Advanced Mode provides more advanced configuration features supported by the devices. This mode allows you to perform more advanced configuration of the devices for installations in which you need more control over the operation of the devices. The first item in the menu is Go to ADVANCED mode. Clicking on this item changes the configuration interface into Advanced Mode. In advanced mode, additional menu items and configuration pages are available, and the first menu item changes to Go to BASIC mode. Clicking on this item reverts back to basic mode. When you are done configuring the DRG200i, you should always log out of the configuration interface by clicking Exit (see Logging Out on page 28). This will take you back to the login page and prevent unauthorized access to the configuration pages. User Accounts and Logging In Before you can configure DRG200i, you need to login using one of the built-in user accounts by providing a user name and a password. Several types of user accounts allow different levels of access: Administrator Account provides full access and allows system administrators to configure all aspects of the DRG200i (see Administrator User Account on page 22). Technician Account provides read-only access to the System Status page and several Diagnostics pages (see Technician User Account on page 23). Limited User Account provides access to only the System Status page and the Radio Diagnostics page (see Limited User Account on page 24). Depending on the user account you use, you can either access all configuration pages or just a subset of the pages. To launch the login page, you can either use the network discovery feature (see Network Discovery on page 18), or type the IP address of the DRG200i into the address bar of your web browser (i.e. either the factory default IP address or the IP address you configured in Getting Started on page 9). The following procedure assumes you are using Firefox ; however, the same steps also apply to other browsers. 20 Basic Configuration

29 To log in to the configuration interface 1 In the address bar of your web browser, type the IP address of DRG200i channel (e.g for Channel A). The login page for the channel is displayed. 2 Click Log in to show the password dialog. 3 In the password dialog, to log in under the administrator account, type omni for the user name, and type drg200i for the password (this is the default password). 4 Click OK to log in. Note The password is case sensitive and must be typed in lowercase characters make sure the Caps Lock key is not active on your computer keyboard. You can also log in under either the Technician account or the Limited-user account: you will need to check with your administrator as to the correct user name and password to use. Once you are logged in, the System Status page will appear showing the current status of the device for that channel. The appearance of the System Status page depends on which account you used to login under (see Viewing the System Status on page 29). DRG200i Product Manual 21

30 You can now access the various configuration pages to check the settings or to make changes to the configuration settings as required. Note If you logged in under the built-in administrator account, you can also change the password used to access the configuration interface (see Changing the Passwords on page 64). Administrator User Account If you login under the Administrator account, you will see the System Status page and menu depicted in Figure 4 on the following page. Under this account, you can configure the basic settings in basic mode and then switch to advanced mode to configure the advanced settings as required (see Advanced Configuration on page 47). This page is the same in both basic and advanced modes. Administrators have unlimited access to the configuration interface and are responsible for configuring the DRG200i and setting up the built-in user accounts. It is recommended that you change the password of the Administrator account to prevent unrestricted access to the configuration interface. 22 Basic Configuration

31 Figure 4. System Status page displayed under the administrator account You should also set up the user name and password for both the Technician and the Limited user accounts as required. When you are done configuring the DRG200i, you should log out by clicking Exit. Technician User Account When you login under the Technician account, only a limited set of menus and basic configuration pages appear as shown in Figure 5. Under this account, you can view the System Version Information and the Current Status. Additionally, you can access some of the configuration pages and several Diagnostics pages. Figure 5. System Status page displayed with the technician account DRG200i Product Manual 23

32 Limited User Account When you login under the Limited account, all of the configuration pages are hidden, and you can only access the System Status, Statistics, and Event Log pages, as shown in Figure 6. Figure 6. System Status page displayed with the limited-user account Configuration Status On all configuration pages, a configuration status area appears along the lower edge of the page. This shows the configuration status for the current page and whether you have made any changes, or the configuration has changed but you have not saved the changes. Figure 7 shows the Configuration Status area when no changes to the configuration are pending. Configuration status Shows the status of the configuration settings Save button Saves configuration Restart button Restarts the device Undo button Discards any changes Reset to Defaults button Restores factory default settings Figure 7. Configuration status area and control buttons The Configuration Status area also provides several control buttons to allow you to save or undo any changes you make to the configuration settings. You can also reset the DRG200i to its factory default settings, and restart the DRG200i. The function of each control button is described below: 24 Basic Configuration

33 Save allows you to save the changes you made to the settings on the configuration page displayed in the web browser. You must always save the configuration before navigating to another configuration page otherwise the changes will be discarded. Restart performs a restart of the DRG200i loading the configuration settings from flash memory a restart is required after you save any the changes to the configuration. Reset to Defaults reloads the configuration with default values for settings on all configuration pages (not just the page displayed in the browser), but does not save the default settings to flash memory. Undo discards any changes that you made to the settings on the configuration page displayed in the web browser, and reloads the configuration. This affects the settings on all configuration pages; not just the settings on the current page. Status messages appear immediately above the buttons. The following list provides a description of each status message. Status Configuration Unchanged Configuration has been saved. Restart required to take effect. Data is invalid: IT HAS NOT BEEN SAVED Configuration reset to defaults: NOT SAVED Configuration reset to saved values Description Indicates that the configuration settings on the page have not changed. Indicates that the configuration settings have been saved into flash memory of the DRG200i, but are not currently used. A restart is required before the new settings will take effect. Indicates that one (or more) of the settings entered was invalid and the configuration has not been saved. All configuration values on a page must be valid before any values will be saved. You must identify all incorrect configuration values and correct the errors. The Configuration Status area will show additional information about the incorrect value. Indicates that the ALL configuration settings have been reset to the default values; not just the settings on this page. However, you still need to save the changes to make the changes permanent. The configuration values on the configuration page have been restored to the values saved in the flash memory. This is the result of clicking the Undo button. Note If you change a configuration setting(s) on a page, you must always save the configuration before navigating to another page otherwise any change(s) you made will be discarded. DRG200i Product Manual 25

34 Saving the Configuration Settings When you make changes to the settings on a configuration page, or you restore the configuration from a backup file, you must save the changes otherwise if you navigate to another configuration page, the changes will be discarded. To save the configuration changes, click Save on the page. When you save the changes, the message displayed under Configuration Status changes to Configuration has been saved. Restart required to take effect, as shown in Figure 8. This means the configuration has been permanently saved, however, you now need to restart the DRG200i so that the new settings can take effect (see Restarting after Saving the Configuration below). Figure 8. Restart required after saving the changes to the configuration Restarting after Saving the Configuration Once you have made changes to the configuration, or restored the configuration from a backup file, and then saved the configuration, you must restart the DRG200i for the changes to take effect. To restart the DRG200i, click the Restart button on the page. Warning! Do not disconnect power to the DRG200i while it is restarting; otherwise it may cause damage to the DRG200i or corrupt the firmware. While the DRG200i is restarting, the page will show Restart in Progress, as shown in Figure 9. Figure 9. Restarting the DRG200i after saving the configuration settings 26 Basic Configuration

35 After about 30 seconds, the DRG200i should restart and you will be redirected to the login page in your web browser. You will then need to log in again if you want to continue configuring the DRG200i (see User Accounts and Logging In on page 20). After restarting the DRG200i, it is recommended that you back up the configuration to a file on your computer in case you need to restore the configuration later (see Backing up the Configuration to a File on page 35). If you can no longer use your web browser to communicate with the DRG200i after restarting the device, it is most likely that the IP address of your computer is now on a different subnet than the DRG200i. If this is the case, you ll need to change it to the same subnet as the DRG200i device before you can use your web browser. For further information on how to change the IP address of your computer, refer to Connecting to the Network on page 9. Note Once the DRG200i restarts, you may need to refresh your web browser to reload the page. Resetting to Factory Default Settings Sometimes you may want to reset the configuration of the DRG200i to its factory default settings. This is especially useful when you want to change only a handful of settings as it provides a good starting point for configuring the device. In most cases, the default configuration will do for basic installations with only some changes to a handful of settings. The default configuration is also useful when you need to troubleshoot a particular problem or the device is not operating as you expected. In this case, you can start with the default settings and carefully make changes as required to determine the cause of the problem. Note When you reset the DRG200i to factory defaults, the network settings such as the IPv4 address, subnet mask, and the gateway, will reset to the factory default settings. Hence, the DRG200i may be on a different subnet than your computer and you might not be able to communicate using your browser. In this case, you will need to temporarily change the network settings of your computer to match those of your DRG200i in order to use your browser to communicate with the device (see Getting Started on page 9). Figure 10 on the following page shows the three steps involved in resetting the configuration of the DRG200i to default settings. The first step in resetting the configuration to default settings is to click Reset to Defaults. This resets the inmemory configuration to the default settings; however, it does not make the changes permanent. The status message changes to Configuration reset to defaults. NOT SAVED. The second step is to save the configuration and make the default settings permanent by clicking Save. The status message changes to: Configuration has been saved. Restart required to take effect. DRG200i Product Manual 27

36 The third and final step in resetting to defaults involves restarting the device by clicking Restart. The new settings will be loaded when the DRG200i restarts. Step 1 Reset configuration to default settings Step 2 Save configuration to make it permanent Step 3 Restart to load default configuration settings Figure 10. Resetting the configuration to default settings Logging Out Once you have completed configuring the DRG200i, it is recommended that you log out by clicking Exit on the menu. This will take you back to the login page in your browser. If you decide you want to continue configuring the DRG200i, you will need to type your user name and password to log in again to access the configuration interface (see User Accounts and Logging In on page 20). 28 Basic Configuration

37 Viewing the System Status Select the System Status menu to display comprehensive status information for the DRG200i. All the values displayed on this page are read-only so you cannot make any changes to these values. If you login under the technician account or the limited-user account, the information displayed will be the same; however, you will not see as many items displayed in the menu (see Technician User Account on page 23 and Limited User Account on page 24 for further details). Figure 11 shows an example of the System Status page when logged in under the administrator account. The information you see here is specific to the digital-radio interface implemented in your DRG200i in this case, it is specific to DMR-AIS (Digital Mobile Radio Application Interface Specification). Common information Shows status information common to all interfaces Interface information Shows status information for specific digital-radio interface Figure 11. System status page for DMR-AIS under the administrator account Most of the information that appears on this page is common to all types of DRG200i digital-radio interfaces regardless of the type of interface you are actually using. The common information appears under the following sections: System Version Information (see System Version Information on page 30) Current Status (see Current Status on page 30) Gateway Connections (see Gateway Connections on page 30) Console SIP Status (see Console SIP Status on page 31) Radio Patching Status (see Radio Patching Status on page 31) DRG200i Product Manual 29

38 Information that appears below these sections depends on the digital-radio interface that you are configuring. For specific information about the interface, refer to the appropriate DRG-Series interface supplement provided with your DRG200i product (this is also available upon request from your local sales representative). System Version Information The System Version Information section displays the version information for the firmware that is currently loaded in the DRG200i. Also displayed here is the revision and serial number of the DRG200i hardware. Current Status The Current Status section displays current status information about the operation of the DRG200i and includes the following: IP Address shows the local Internet Protocol (IP) Address of the DRG200i. Ethernet MAC Address shows the unique Media Access Control (MAC) address of the DRG200i. System up time or elapsed time since the DRG200i was last reset (displayed as days, hours, minutes and seconds). Free memory shows the unused memory in bytes available in the DRG200i. Largest free memory shows the single largest chunk of memory that can be allocated by the firmware at this point in time. Free blocks shows the number of free memory blocks available the remaining free memory is divided into blocks and is used as an indication of memory fragmentation. Used memory shows the memory in use or allocated in bytes. Largest used memory shows the single largest chunk of memory currently in use or allocated. Used blocks shows the number of memory allocations that have been made and not yet released. Connected IP devices shows the number of IP devices communicating with the DRG200i device. This number includes connected IP devices that are not currently transmitting audio. Gateway Connections The information displayed under Gateway Connections shows all the connections from Omnitronics dispatch consoles to this DRG200i, and includes the following: Connection 1 to Connection 4 show all the connections from Omnitronics dispatch consoles to this DRG200i. In a DX-Altus system, you would normally expect two connections: one from each System Control Unit (SCU) in the DX- Altus Server sub-rack. 30 Basic Configuration

39 Console SIP Status The Console SIP Status section appears only if you enable SIP operation (see Advanced SIP Settings on page 59), and shows the current status of the SIP connections as follows: Current active connections shows the number of active SIP connections. Status shows the status of the SIP connection to the Omnitronics console system. Possible status values include: Idle Accepted incoming call: RTP Remote address:port Call Terminated No call currently in progress. Accepted incoming call where address is the IP address of the remote console system and port is the UDP port number for the connection. The call has been ended. Radio Patching Status The Radio Patching Status section shows information about the patch group(s) in which this DRG participates, as shown in Figure 12. Figure 12. Radio Patching Status Patch Groups Total shows the total number of patch groups in the system. If the system does not have any patch groups, this will show zero. Patch Group Name is the name of the patch group in which this DRG participates, and shows whether this patch group is [ON] or [OFF]. The other devices included in the patch group appear in a list showing their IPv4 addresses and ports. This example shows three devices participating in the patch group. DRG200i Product Manual 31

40 Configuring the Basic Network Settings Select Network in Basic Mode to display the basic Network Configuration page, as shown in Figure 13. Use this page to configure the basic network settings, such as the IP address, network mask, and the gateway address of the DRG200i. Figure 13. Basic network configuration Basic Network Settings The Basic Settings and the Network Settings sections allow you to configure the basic network settings of the DRG200i and include the following: Location Name is the name assigned to the installation site. It is also the name that will appear in the Windows Network Neighborhood and can also be used to access the device by name on a local network. This setting consists of alphanumeric characters up to a maximum length of 100, but must not contain any spaces or punctuation characters. The default name is the type of device followed by its serial number. For example, a DRG200i device with a serial number of would have the default name of DRG200i Automatically obtain IP Address (using DHCP) option is used to allow the DRG200i to obtain an IP address automatically from a DHCP server. When DHCP is enabled, the static IP address, network gateway address, and the domain name server settings will be ignored as appropriate values will be provided by the DHCP server. When this option is selected, the other network settings will be disabled. The default setting is disabled. 32 Basic Configuration

41 Static IP Address is the IPv4 address of the DRG200i, which consists of 32 bits expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. The default value is or (the default configuration is to use a static IP address). Note If the Omnitronics console connection (RediTALK-Flex or DX-Altus IPE) to the DRG200i is via a unicast RTP connection, the DRG200i must use static IP addresses. If you use the option to Automatically obtain IP Address (using DHCP), the DRG200i will attempt to locate a DHCP server at start up. If it cannot find a server, it will either use the static IP address or automatically assign an address in the range x.x. Omnitronics does not recommend using DHCP mode as it means the DRG200i may fail to work when the DHCP server is not available. Netmask is the subnet mask that determines what part of the IPv4 address is used to identify the subnet that the DRG200i is on. A valid IPv4 subnet mask consists of 32 bits: a sequence of ones (1) followed by a block of zeros (0), expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. The sequence of ones (1) designates that part as the network prefix (subnet) and the block of zeros (0) designates that part as the host identifier. The default value is Gateway Address is the IP address of the default network gateway. This would usually be the IP address of the router or network device that provides access to the WAN or internet. A valid IPv4 gateway address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. The default value is Using a DHCP Server Select Automatically obtain IP Address (using DHCP) to enable Dynamic Host Configuration Protocol (DHCP), which allows the DRG200i to obtain an IP address automatically from a DHCP server. When DHCP is enabled (disabled by default), the static IP address, network mask (netmask), and network gateway address settings will be ignored as appropriate values will be provided by the DHCP server. If you want to assign a static IP address (the default setting), clear this option and type the static IP address, netmask, and gateway address. It is recommended that you allocate an address in the range of to or to as these are especially reserved for private addresses. When using DHCP, another IP device will not be able to communicate with the DRG200i unless you use multicast addressing as it will not know the IP address allocated by the DHCP server. Both of these are discussed below: Multicast Addressing is a protocol for efficiently sending data to multiple DRG200i devices at the same time over TCP/IP networks (see Multicast Addressing on page 43 for further details). DRG200i Product Manual 33

42 Although VoIP devices and dispatch consoles configured to use multicast addressing will be able to transmit voice data to/from a DRG200i configured with DHCP, they will not be able to access the DRG200i s digital radio functions. Digital radio functions of the DRG200i are accessed by connecting to the Omnitronics Gateway Interface TCP port (see Omnitronics Gateway Interface on page 39). Connecting to this port is only possible with a static IP address connection. Therefore, enabling DHCP is not recommended for general use. Backing up and Restoring the Configuration Select Backup/Restore on the menu to display the page shown in Figure 14. The options on this page allow you to back up the configuration to a file, or restore the configuration from a file, on the hard disk of your computer. It is recommended that you back up the configuration for safe-keeping, in case it needs to be restored later. When the configuration is restored from a backup file, it needs to be saved to the DRG200i to make the changes permanent. The next time the DRG200i restarts, the restored configuration will take effect. Figure 14. Backing up and restoring the configuration 34 Basic Configuration

43 Backing up the Configuration to a File Once you have completed making changes to the configuration settings, it is recommended that you back up the configuration to a file on your computer for safe-keeping. You will be prompted to select a location on your computer to store the backup file. The default file name is drg220i_dmr_ais_cfg.bin, but you may rename the file. The following procedure assumes you are using Firefox as your web browser; however, other browsers will show similar screens. To back up the configuration 1 On the Configuration Backup/Restore page, click Backup to open the browser s Save File dialog. 2 Select the Save File option (if not already selected). 3 Click OK to save the configuration. You will be prompted for a folder and file name in the browser s Enter name of file to save to dialog. 4 (Optional) If you want to use a different folder or file name other than the default (drg200i_dmr_ais_cfg.bin), type the file name in the File name box. 5 Click Save to download the configuration and save it to the specified file. When the download is complete, the file will appear in the browser s Downloads dialog similar to the one shown below. 6 Click Close. The configuration should now be backed up to the specified file. DRG200i Product Manual 35

44 Restoring the Configuration from a File You can restore the configuration to a previously backed up configuration (backup) by restoring it from a backup file on your computer. Once you have restored the configuration, you must save it by clicking Save to make the settings permanent, and then restart the DRG200i by clicking Restart for the settings to take effect. Note Restoring the configuration only loads it into memory: it does not permanently save it. You must save the configuration after you restore it to make it permanent, and then restart the device for the configuration to take effect. The following procedure outlines how to restore the configuration and assumes you are using Firefox as your web browser; however, the procedure will be the same for other browsers. To restore the configuration 1 On the Configuration Backup/Restore page, click Browse to open the browser s File Upload dialog. 2 In the File Upload dialog, locate the backup file (drg200i_dmr_ais_cfg.bin), and then click Open. The full path and filename of the file you selected is displayed. 3 Click Restore to restore the configuration from the backup file. The Configuration Status changes to Configuration restore complete! (Configuration has not been saved). 36 Basic Configuration

45 4 Click Save to save the configuration. This saves the configuration, but it will not take effect until you restart the DRG200i. The Configuration Status changes to "Configuration has been saved. Restart required to take effect". 5 Click Restart. The Restart in Progress page appears while the DRG200i restarts. The login page will then be displayed in your web browser (see Restarting after Saving the Configuration on page 26). DRG200i Product Manual 37

46 Digital Radio Configuration Select Digital Radio in Basic Mode to configure the digital-radio interface for the digital radio attached to the DRG200i, as shown in Figure 14. Figure 15. Digital radio configuration The DRG200i supports several different types of widely-used digital-radio interfaces. The digital radio configuration will be different for each type of interface supported. Therefore, the configuration settings provided by the DRG200i depends on the interface it supports. For a list of all the digital-radio interfaces currently supported by the DRG200i, refer to Features on page 2 or contact your local Omnitronics Sales Representative for further information. 38 Basic Configuration

47 Omnitronics Gateway Interface The following setting appears under Omnitronics Gateway Interface: TCP Port Number is the port that the DRG200i uses for incoming TCP connections the DRG200i acts as a TCP server accepting incoming connections on this port from other Omnitronics devices. Digital Radio Settings This group of configuration settings determines whether a specific capability is published to the DX-Altus Server or RediTALK, and is therefore available to the end user of Alto or RediTALK. Note Most of these settings are common between interfaces. Some settings may not be supported by your DRG200i depending on the interface implemented. Functions specific to a particular interface are described in the appropriate DRG-Series Supplement for the digital radio it supports (available upon request from your local Sales Representative). Disable Channel Change option allows you to disable the capability to change the channel on the radio (this capability will be preconfigured by software provided by the radio manufacturer). Disable Call Alert option disables the ability for the console operator to send an alert to another radio. A call alert allows the console operator to send an alert to another radio requesting that the radio operator call back the console operator (the radio operator acknowledges the alert by pressing PTT). Disable Individual Call option disables the ability to initiate an individual call from a console. Disable Individual Call Timeout option disables individual-call timeouts. Individual Call Timeout is the time (in seconds) that the DRG200i will wait for individual-call activity before it cancels the individual call and reverts to broadcast mode. This timeout is only used when the Disable Individual Call Timeout option is not selected. Enable Confirmed Individual Call option allows the console operator to manually answer (pick up) Individual Calls. Confirmed Individual Call Timeout is the timeout (in seconds) that the DRG will wait for the operator to manually answer the Individual Call. Disable Group Call option disables the ability to initiate a group call from a console to a group of radios. Disable Group Call Timeout option disables group-call timeouts. Group Call Timeout is the time (seconds) the DRG waits for group-call activity before it cancels the group call and reverts to broadcast mode. This timeout is only used when the Disable Group Call Timeout option is not selected. DRG200i Product Manual 39

48 Disable All Call Timeout option disables the All Call timeout and allows the console operator to immediately setup a new call without the need to wait or cancel the All Call. If the timeout is enabled, it implies that the console operator will have to either first cancel the call (only applicable to P25) or wait for the timeout to expire (P25, MotoTRBO, and IDAS). All Call Timeout is the time (in seconds) that the DRG200i will wait for all call activity to cease before it reverts to broadcast mode. This timeout is only used when the Disable All Call Timeout option is not selected. Call Setup Timeout is the timeout applied to set up a call when the console operator does not PTT within a reasonable time (see Figure 16 on page 41). If PTT occurs within the timeout, the DRG will setup the call. However, if PTT timeout occurs, the DRG will revert to its default call. If an incoming call is received, the DRG will accept the call and cancel the operator s request (the operator will need to request the call type after the incoming call ends). Disable Emergency option disables access to the Emergency feature from the DRG200i and any connected dispatch consoles such as Alto. Disable Text Messaging disables the ability to send a text message to a specific radio or to a group of radios. Disable Radio Status Message disables access to the Status Message feature from the DRG200i and any connected dispatch consoles such as Alto. Disable Poll Radio Status disables access to the Poll Radio Status capability from the DRG200i and any connected dispatch consoles such as Alto. Disable Radio Check disables access to the Radio Check capability from the DRG200i and any connected dispatch consoles such as Alto. Disable Stun Radio disables access to the Stun Radio capability from the DRG200i and any connected dispatch consoles such as Alto. Disable Revive Radio disables access to the Revive Radio capability from the DRG200i and any connected dispatch consoles such as Alto. Disable Kill Radio option disables access to the Kill Radio capability from the DRG200i and any connected dispatch consoles such as Alto. The Kill Radio capability renders a remote radio permanently disabled. Disable Monitor Radio disables access to the Monitor Radio feature from the DRG200i and any connected dispatch consoles such as Alto. Disable Tone Generation disables access to the Tone Generation feature from the DRG200i and any connected dispatch consoles such as Alto. Enable Radio Linking option enables the radio-linking capability, and when enabled on at least two channels supported by your DRG firmware, it allows a RediTALK-Flex operator to link audio between these channels. Enable Radio Patching option enables the Radio Patching capability that dynamically forwards incoming radio audio to other network devices. You also need to ensure that conference mode is enabled (see VoIP Conference Mode on page 56); otherwise, under the Radio Patching Status, you will see Radio Patching is disabled because conferencing is disabled. 40 Basic Configuration

49 Call timeouts are illustrated in the timing diagram of Figure 16 this timing diagram applies to the digital-radio interfaces. Each call type (IND, GRP, ALL) can be configured independently. The purpose of the timeout is to maintain the call type and recipient during overs until there is no activity (BUSY/PTT) within a specified time window. Call timeout can be enabled or disabled for each call type. If disabled, the DRG200i will apply the default call configuration (All Call) as soon as PTT/BUSY is cleared. Figure 16. Digital radio timing diagram If the timer is not disabled, the DRG200i will maintain the call type and recipient and reset this timer after every over. If the timer is allowed to expire (no one pressed PTT within the timeout), the DRG200i will revert to the default call type. This implies that the next PTT will then setup an All Call. If the timer expires while a BUSY/PTT is active, the timer restarts. Keep in mind that the radio itself may have similar timers that the firmware cannot interrogate, and if these timers clash with those of the DRG200i, the DRG200i will not behave as expected. It is advisable to set the DRG200i timers greater than the actual radio timers. DRG200i Product Manual 41

50 VoIP/RTP Configuration Select VoIP/RTP in Basic Mode to configure the basic settings for VoIP and RTP, as shown in Figure 17. Figure 17. Basic VoIP/RTP configuration The basic settings include the IP address of the remote DRG device and port numbers used for data exchange. Basic Settings The basic settings on this page include the following: Remote IP Address is the IPv4 address of the remote DRG200i, which consists of a valid IPv4 address, or a fully-qualified domain name. The default value is the local address of a matching DRG device (see Types of Remote Addressing below). Note This is only for unicast or multicast operation. For SIP-only operation, set this to When configuring a direct connection to a remote VoIP device, such as the DX-Altus IPE (in LIU mode) or another DRG, you specify its IP address. However, if this DRG is used exclusively with RediTALK-Flex consoles, which connect via SIP, set this address to This address should never be set to the address of a remote VoIP device that uses SIP to initiate a connection (e.g. RediTALK-Flex). RTP receive port number is the Internet port number that is used for receiving audio and control messages. The allowed value is an even number from 1024 and The default setting is 5004, 5006, 5008 or 5010 (depending on the VoIP Channel/Group number). 42 Basic Configuration

51 RTP transmit port number is the Internet port number that is used for transmitting audio and control messages. The allowed value is an even number from 1026 and The default setting is 5004, 5006, 5008 or 5010 (depending on the VoIP Channel/Group number). Types of Remote Addressing The Remote IP Address can be one of the following formats: Numeric Address is an IPv4 address, which consists of 32 bits expressed in a form consisting of four decimal octets separated by periods (dots), called dotdecimal notation. This can be used on a LAN set up where all the addresses are allocated. Numeric addressing can also be used where a global Internet Address has been allocated and is known. On a local LAN, a common numeric address could be either or You may also use a multicast address (see Multicast Addressing on page 43). The special address disables transmission this can be useful in a DRG200i that uses SIP to connect to a dispatch system (see Session Initiation Protocol (SIP) on page 95). Fully Qualified Address is an internet address that uses a fully-qualified domain name like dgr100unit3.host.omnitronics.com.au. You can only use a domain name if the DRG200i has been configured to use a domain name server (DNS). In this case, the address of the remote DRG device will be allocated by a DNS. This could be the case for an DRG device that is connected to the Internet via an ADSL modem. Multicast Addressing Multicast Addressing (multicasting) is a numeric IP addressing scheme that provides an efficient method of sending audio to multiple destinations (a one-to-many transmission). Using multicast addressing, a single data packet is routed to multiple destinations; and the network will only duplicate the packet if it needs to go to several different locations. To configure a DRG200i to use multicast addressing, you set the remote address to a numeric multicast address. The DRG200i will then join the multicast group associated with this multicast address and will communicate with all devices in the multicast group. For multicast addressing to work effectively, all the network routers in the network must support multicast addressing and have multicasting enabled in their configurations. If your network does not support multicasting, you can use conference mode to provide an alternate solution. For further information about conference mode, refer to VoIP Conference Mode on page 56. Audio received at any DRG200i in the multicast group is transmitted once and received by all the other DRG200i devices in the group. Effectively all the radios or consoles are linked together. If any one DRG200i device fails, only that DRG200i is affected. All the devices are configured to use a single multicast address as the remote address for their VoIP link. For further information about multicast addressing, refer to Multicast Addressing on page 88. DRG200i Product Manual 43

52 Note Some consumer and business routers (and many ADSL/DSL modems) on the market do not support multicasting. Internet Port Numbers An Internet port number is part of the IP header and identifies the type of data. The port numbers 5004 and 5005 are allocated for the Real Time Protocol (RTP) and are normally used for VoIP and video data packets. However, the port number may need to change in order to pass through some types of network devices, particularly those that use Network Address Translation (NAT) or Port Forwarding. SIP Configuration Select SIP in Basic Mode to configure the basic settings for the Session Initiation Protocol (SIP), as shown in Figure 18. The settings on this page relate to incoming SIP connections (see Session Initiation Protocol (SIP) on page 95). Figure 18. SIP configuration settings SIP Basic Settings The settings available under SIP Settings include the following: Enable SIP enables support for SIP (Session Initiation Protocol). Selecting this option will allow a particular channel of the DRG200i to accept up to 12 incoming connections (for a total of 24 connections across the two channels if both have Enable SIP selected) from other Omnitronics products, such as the IPR110Plus and RediTALK-Flex. The default setting is disabled. 44 Basic Configuration

53 Disable incoming connection option prevents incoming SIP connections from DRG devices and consoles. SIP Port is the port number used for SIP connections. The allowed values are 1025 to The default value of 5060 is the port assigned by the Internet standards body for SIP. Note The SIP Port must match the setting used by the device that will connect to the DRG200i; and the value must be different to the port numbers used by the VoIP/RTP configuration. Default Transport Protocol is the default transport protocol used for transmitting SIP messages. The DRG200i supports both the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). This option is for compatibility with devices and servers that only support one of these transport protocols. Regardless of the value of this setting, the DRG200i will correctly respond to SIP messages sent to it using both UDP and TCP transport protocols. Allowed values are: UDP - User Datagram Protocol, TCP - Transmission Control Protocol. Default is: UDP - User Datagram Protocol. Note This setting only appears for firmware that supports both the UDP and TCP transport protocols this setting does not appear for the older firmware, which only supports the UDP transport protocol. User Name is the name that is used to validate an incoming SIP connection. If an incoming SIP connection does not have the correct user name it will be rejected. A unique user name is assigned to each local VoIP Group. A valid user name may consist of alphanumeric characters (no spaces or punctuation characters allowed). The default name is drg.

55 Advanced Configuration This chapter discusses the advanced settings of the DRG200i, and includes the following sections: Switching to Advanced Mode Advanced Network Settings on page 48 Simple Network Management Protocol (SNMP) Settings on page 51 Advanced VoIP/RTP Settings on page 53 Advanced SIP Settings on page 59 Changing the Passwords on page 64 Switching to Advanced Mode Advanced mode provides many additional settings and features beyond those available in the basic mode. To use the advanced mode, select Go to ADVANCED mode as shown in Figure 19. This reloads the current page in your web browser to show the advanced configuration settings for the page. Figure 19. Switching to advanced configuration mode of the DRG200i To switch back to the basic mode, select Go to BASIC mode on the menu (see Basic Configuration on page 17). In Advanced mode, the following additional items appear on the menu: SNMP, SIP. Many of the configuration pages provide advanced settings. For example, in the advanced mode, the Network Configuration page displays additional settings under the Advanced Settings heading and the Dynamic DNS heading. Some pages, however, do not have any advanced settings so you will see the same settings in the advanced mode that you see in the basic mode. All of the Diagnostic pages, with the exception of the Connections page, are the same in basic mode and advanced mode: the Connections page is only available in the advanced mode. DRG200i Product Manual 47

56 Note The advanced and basic modes only affect what settings are displayed on the web pages: basic mode does not disable any advanced mode features or settings. Advanced Network Settings Select Network in advanced mode to configure the advanced network settings, as shown Figure 20. This page consists of two additional sections: Advanced Settings, and Dynamic DNS. The Basic Settings and Network Settings are already covered under the basic network settings (see Configuring the Basic Network Settings on page 32). Figure 20. Advanced network configuration Note If you make any changes to the settings on the Network Configuration page, you must save the configuration and then restart the device for the changes to the network settings to take effect. Advanced Settings The Advanced Settings section allows you enable the Universal Plug and Play (UPnP) technology to make it easy for devices to discover each other on the network, and various other advanced settings including the following: 48 Advanced Configuration

57 Enable UPNP selects the Universal Plug and Play (UPnP) feature, which is a networking technology that allows devices to work together with fewer configurations. By enabling UPnP, the DRG200i will be displayed in the Network Neighborhood on a Microsoft Windows computer. The default setting is enabled. Enable Telnet option allows remote access using Telnet. The default setting is disabled. Note You should disable the Telnet option when you do not require remote access or when the DRG is connected to a public IP network such as the Internet. Domain Name System (DNS) Server 1 is the primary Domain Name Server (DNS). This is how an Internet address, such as is converted into a numeric (dot-decimal notation) address, like Consult with your ISP or network administrator to determine the correct address. In some cases, the DNS address is the same as the Gateway address. If the VoIP remote address is a numeric value, you do not need to change this setting. A valid IPv4 address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). A value of indicates that no DNS is used. The default setting is (not used). Domain Name System (DNS) Server 2 is the backup DNS that is used in the event the primary DNS is not available. A valid DNS address is the same as described for the setting above. A value of indicates that no DNS is used. The default setting is (not used). Quality of Service: Differentiated Service Class allows the DRG200i to mark its VoIP packets as higher priority to ensure they receive preferential treatment when being routed. Consult with your ISP or network manager for more information about the appropriate QOS settings. Allowed values: Default, Expedited Forwarding, Class 1 7, Assured Forwarding 1-1 to Assured Forwarding 4-3. The default setting is Default. Syslog host address is the address used for debugging and diagnosing faults with the DRG200i, which can report debug and error information via a network protocol called SYSLOG. This setting is normally set to the default (not used). A valid IPv4 address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). A value of indicates that no SYSLOG messages are used. The default is (not used). DRG200i Product Manual 49

58 Dynamic DNS The Dynamic DNS area allows you to configure the DNS settings of the DRG200i and includes the following: Enable Dynamic DNS allows the device to track changes in its public IP address and to update the configured Dynamic DNS host accordingly. Additionally, it performs periodic Domain Name resolution of any configured remote domains and performs required adjustments when a remote end experiences a change in public IP address. Enabling this feature will decrease VoIP down-time when devices sit behind routers of which the IP address can change dynamically. The default is disabled. Note When enabling Dynamic DNS, ensure that the Domain Name System (DNS) Server 1 is configured to an actual DNS server. To enable period DNS resolution only, select this setting and leave all the following settings blank. Public IP Service 1 is a URL to a web service that returns the current public IP address of the requester. It must start with and it is best to verify this in a browser before copying the URL to this setting. Service 1 will act as the primary web IP lookup. Leaving this field blank will disable determining the DRG device s public IP address. The default is Not Configured. Public IP Service 2 is similar to Public IP Service 1 except that this will act as the secondary web IP lookup if configured. It will only be used if Service 1 fails. The default is Not Configured. Device Domain Name is the fully qualified domain name of the device. It is this name that is used in all dynamic DNS updates when the device detects a change in the current public IP address. The default is Not Configured. Dynamic DNS Host Domain Name is the fully qualified domain name of the server hosting the Dynamic Domain Name service. The server must be the authority with which the Device Domain Name is registered. The default is Not Configured. Dynamic DNS Host Port is the HTTP port (usually 80) of the server hosting the Dynamic Domain Name Service. If port 80 is blocked by a local firewall and if the Dynamic Domain Name Host allows updates via another port, set this accordingly. The default port is 80. Dynamic DNS Host Authentication User Name is the user name required by the dynamic DNS Host for authentication in all updates. The default is Not Configured. Dynamic DNS Host Authentication Password is the password required by the dynamic DNS Host for authentication in all updates. The default is Not Configured. Use the Public IP address for SIP determines whether the public IP address of the device will be used in all SIP conversations. If this setting is not selected, the private IP address will be used. This setting is not selected by default. 50 Advanced Configuration

59 Simple Network Management Protocol (SNMP) Settings Select SNMP in advanced mode to configure the SNMP (Simple Network Management Protocol) settings, as shown in the Figure 21. Figure 21. SNMP configuration The SNMP configuration of the DRG200i includes the following parameters: Enable SNMP selects the Simple Network Management Protocol (SNMP) feature. SNMP provides a means to extract status information from the DRG200i through a network management system. The DRG200i provides several standard network statistics as well as the site monitoring and control I/O of the DRG200i. If SNMP is not being used, this setting should not be selected. For more information about SNMP, refer to Simple Network Management Protocol (SNMP) on page 97. Read community is the SNMP authentication password needed to read (SNMP GET) values from the DRG200i. The default community is "public". If left blank, the DRG200i will set this value to "public" when you save the configuration. It is important to note that in order to write (SNMP SET) values to the DRG200i (the digital outputs are the only values allowed), the community "omni" is required. The SET community cannot be changed. Trap destination and Trap destination 2 specify the IP address to which the DRG200i will send SNMP traps. This is also known as an SNMP trap sink address. Generally, it is the IP address of a machine that hosts network management software (NMS). The SNMP Trap destination can only be a valid static IP address. By default, the address is which disables SNMP traps. DRG200i Product Manual 51

60 Enable VoIP statistic traps enables the VoIP SNMP Receive statistic reports section of the webpage, including the SNMP statistics interval parameter. Selecting this checkbox will enable the DRG200i to send a periodic SNMP trap (defined in the SNMP statistics interval) for a specific VoIP Group if either: a) the number of defined RTP Sequence errors is attained for a particular VoIP group; or b) the number of defined RTP Packets too late is attained for a particular VoIP group. Note The counters for each of these conditions will reset every time the SNMP statistics interval has been reached. SNMP statistics interval specifies in seconds when the DRG200i will send an SNMP trap for a specific VoIP Group if either: a) the number of defined RTP Sequence errors is attained for a particular VoIP group; or b) the number of defined RTP Packets too late is attained for a particular VoIP group. Note The counters for each of these conditions will reset every time the SNMP statistics interval has been reached. The default value is 900 seconds (15 minutes). VoIP receive sequence errors report threshold and VoIP receive packets too late report threshold defines how many RTP sequence errors or how many RTP packets that arrive too late are permitted within the SNMP statistics interval for a particular VoIP group. Generally, RTP sequence errors and RTP packets that arrive too late may occur during bad network conditions including slow networks, networks with high packet loss, networks with high packet jitter, or networks with many routers/switches between devices. The default value for these fields is 0 (disabled). 52 Advanced Configuration

61 Advanced VoIP/RTP Settings Select VoIP/RTP in Advanced Mode to configure the advanced settings for VoIP and RTP, as shown in Figure 22. Figure 22. VoIP/RTP advanced configuration Advanced Settings The settings under Advanced Settings include the following: Transmit Codec is the encoding scheme used to encode the audio data for transmission to the remote device. This does not affect the codec used for decoding audio data this DRG will determine the type of codec used by the remote device and decode the audio accordingly even if a different codec is used. The following codecs are supported: G.711 PCMU (default), G.711 PCMA, G ADPCM, or GSM (see Supported Codecs on page 55 for a description of each codec). Note Different versions of IPR devices and VoIP phones can support different codec types. The DRG200i product does not support G.729 or G codecs. DRG200i Product Manual 53

62 IP Time To Live (TTL) determines the number of network routers that will pass on the data packets from this unit. This value limits how far the message will be sent. Typically as a router forwards a data packet, it will decrease the TTL information in the data packet, and once the TTL reaches zero, the message will no longer get forwarded. Allowed values: 1 to 255. Default value: 1. When using multicasting, the TTL value indicates the scope or range in which a packet may be forwarded. When configuring a DRG device to use multicasting, it is important to consult with the IT department that manages the network infrastructure to make sure an appropriate value is used. The following pre-defined values are used by convention: TTL = 0 TTL = 1 TTL = 32 TTL = 64 TTL = 128 TTL = 225 Restricted to the same host Restricted to the same subnet Restricted to the same site Restricted to the same region Restricted to the same continent Unrestricted Minimum jitter buffer size sets the delay in milliseconds imposed on the received audio. If the DRG200i is used on a network in which variations in packet delay occur, increasing this value to match the maximum likely delay should improve the quality of the audio. The larger this value is set, the more delay is imposed on the received audio. The allowed values are 20 to 1000 milliseconds. The default value is 20 milliseconds. Maximum jitter buffer size sets the maximum acceptable audio delay (in milliseconds), for received audio. The DRG200i will automatically adjust the delay (depending on network conditions) to the smallest possible value, thus reducing the received audio delay to the minimum that the network can support. The allowed values are: 100 to 2000ms. The default value is 500ms. Note The Maximum Jitter Buffer Size must be greater than or equal to the Minimum Jitter Buffer Size.. RTCP Interval/Timeout specifies the period (in seconds) when the RTCP packets are sent. The VoIP link consists of voice data and control information. The control information is provided by the Real Time Control Protocol (RTCP) where packets are periodically sent to provide a heart-beat that maintains the VoIP connection. This parameter must be set identically on both devices that have a VoIP link is established. If multicasting is used, all devices in the multicast group must have this parameter set identically. Reducing the value of this parameter has the effect of reducing the time required in detecting a link disconnection with the disadvantage of increasing the required Ethernet bandwidth. Alternatively, increasing the value of this parameter reduces the required Ethernet bandwidth and increases the time to detect a disconnection. An increased RTCP interval may be useful in bandwidth-critical application such as a VoIP link through the 3G mobile phone network. Allowed values: 1 to 120 seconds. Default value: 5 seconds. 54 Advanced Configuration

63 BUSY/PTT periodic transmit disable option disables the periodic transmission of Busy and PTT status information. In normal operation, the DRG device will send the state of the Busy input and Push-To-Talk output to all connected devices to ensure that the current state is always correct. However, in some scenarios, such as expensive satellite IP links, it may be desirable to disable this feature. In this case, Busy and PTT changes are only sent when the state of the input or output actually changes. BUSY/PTT periodic transmit time determines the period (in seconds) at which the DRG device sends the state of its Busy input and Push-To-Talk output to connected VoIP devices. Enable digital radio RTP extension option enables the digital radio RTP extension. When this option is selected, the DRG sends additional information about digital radio calls in the RTP stream. In particular, when radio patching is enabled, the Radio ID is transferred in the RTP stream. Enable encryption allows the DRG200i to encrypt the network data so that a third party is not able to intercept and listen to conversations. Using an encryption algorithm and enabling encryption allows the DRG200i to encrypt all voice and control data. The DRG200i supports the DES standard with a secret key of 56-bits. The allowed values are listed below. Encryption Disabled Encryption Enabled DES Do not use data encryption (the default) Use DES 56-bit encryption Encryption key is used to encrypt the data. This ensures that no third party can decrypt the VoIP data. If this field is blank, the default encryption is used. The encryption key is case-sensitive. Note All communicating DRG and IPE devices must have encryption enabled and use the same encryption type and key; otherwise the devices will not be able to communicate and the VoIP link will fail, as indicated by the VoIP Link indicator on the front panel not illuminating. Supported Codecs The codecs supported by the DRG200i device are listed below: Codec G.711 PCMU 8000Hz μ- law (often u-law, ulaw, or mu-law) G.711 PCMA 8000Hz a- law G GSM Description ITU G.711 Pulse Coded Modulation μ-law. Bandwidth: 64kbps. Use this Codec for tone signaling. Voice Quality: Best. Used in North America and Japan. ITU G.711 Pulse Coded Modulation A-law. Bandwidth: 64kbps. Use this Codec for tone signaling. Voice Quality: Best. Used in Europe and rest of the world. Adaptive PCM: This is ITU G ADPCM 8000Hz: Adaptive PCM. Bandwidth: 32kbps. Voice Quality: Good This is GSM Codec. Bandwidth: 13kbps. Voice Quality: Good for Voice but distorts tones and DTMF signals. DRG200i Product Manual 55

64 VoIP Conference Mode Distributed audio over an IP network is typically transported using multicasting. However, some IP networks may not be able to support this due to conflicts within the existing network. To overcome the inability to use multicasting, you can use conferencing instead. Conferencing is a method of interconnecting multiple VoIP devices over an IP network via a DRG configured for conferencing. All remote VoIP devices in the conference communicate via the conference DRG. When conferencing is enabled, depending on which conference mode you select will determine whether the DRG forwards VoIP data sent from one device to all the other devices in the conference. Note VoIP conferencing is relevant when multiple consoles (RediTALK- Flex and Alto) connect to the same DRG (so they can hear transmissions from other consoles); and when connecting DRGs and IPRs together with or without consoles involved. Under the Conference Mode settings shown in Figure 23, you can configure the DRG200i to connect with multiple IP devices in conference mode. This allows for up to four remote VoIP devices (IPE, IPR100/IPR110Plus) and consoles (960CC/960CSD) to interconnect in a conference using unicast connections. Figure 23. VoIP conference mode settings Enable Conferencing enables the conferencing mode. When conferencing is enabled, the DRG will act as the conference device and will forward VoIP data to the other VoIP devices in the conference in accordance with the conference mode selected. The default is disabled. Conference Mode selects the type of conferencing you want to use and can be either Audio Linked or Audio Unlinked. These modes are only relevant for VoIP data sent from a VoIP device in the conference to the DRG for radio transmission (regardless of whether or not it s connected to a radio); and determines whether or not the VoIP data is forwarded to the other devices in the conference. Default setting: Audio Linked. Audio Linked The conference DRG forwards the VoIP data sent from any VoIP device in the conference to all the other VoIP devices in the conference. Use this mode to link the VoIP data from multiple consoles together thereby linking the audio between the consoles. 56 Advanced Configuration

65 Audio Unlinked The conference DRG does not forward the VoIP data sent from any VoIP device in the conference to the other VoIP devices in the conference. Use this mode when you do not want to link the audio from multiple consoles together. Note On DRGs offering four audio modes, it is recommended you use either the Bridge Server: audio linked mode or the Dispatch Server: audio not linked mode depending on whether or not you want to link the audio (the descriptions above also apply to these modes). The other two modes Peer to peer: no central server and Gateway: audio linked are special implementations and are not recommended. Enable associates the IP address and port configuration for conference-mode transmissions. The default value is disabled. Important You should only enable conferencing for remote VoIP devices that use unicasting to connect with the conference DRG: it should not be used for remote VoIP devices that use SIP. IP Address is the IPv4 address of the remote VoIP device you want to participate in the conference. The device must connect to the conference DRG using a unicast connection (not a SIP connection). Such devices include the DX-Altus IPE (in radio LIU mode) with Alto consoles, IPR100 and IPR110Plus single-channel VoIP devices. RediTALK-Flex consoles connect via SIP sessions, which automatically create a conference, and therefore do not need to be included. This setting can be a numeric (dot-decimal notation) address or a domain name. Allowed values: valid remote VoIP address. Default: to Transmit Port is the IP (even-numbered) port used to send VoIP audio from the conference DRG to the remote VoIP device participating in the conference. Note that two consecutive ports are used for the endpoint: the first port is for the actual audio data (the even-numbered port specified here) and the other (odd-numbered) port is for control and status information, which is automatically allocated as the next available port. Allowed value: an even number from 1026 to Default port: Connecting Multiple Devices in a Conference In the context of conferencing, the term linking refers to VoIP linking, which is only relevant for data sent from a VoIP device to the Conference DRG for radio transmission (regardless of whether it s connected to a radio). When in linked mode, the VoIP data sent from any VoIP device in the conference to the Conference DRG for radio transmission will also be forwarded to all other VoIP devices in the conference. When in unlinked mode, the VoIP data sent for radio transmission will not be forwarded to the other VoIP devices in the conference. DRG200i Product Manual 57

66 Both the linked and unlinked conference modes behave exactly the same in terms of audio received from the radio: typically, the Conference DRG receives the audio, converts it to VoIP data, and then forwards it to all the other VoIP devices in the conference. Figure 24 illustrates the difference between the two conference modes and how the audio is forwarded to the other devices in the conference when a RediTALK-Flex operator transmits (IP Addresses for illustration purposes only). In the Audio Linked mode, the VoIP data (transmit audio) is forwarded to all the other VoIP devices in the conference; whereas, in the Audio Unlinked mode, the VoIP data (transmit audio) is not forwarded.

VoIP audio paths in a conference 58 Advanced Configuration

67 Note If the DRG is used exclusively with RediTALK-Flex consoles, which connect via a unicast SIP session, you should set the Remote IP Address setting of the conference DRG to (see Remote IP Address on page 42). This address should never be set to the address of a remote VoIP device that connects via a SIP session. If you want to use the conference DRG with multiple console systems (DX-Altus or RediTALK-Flex), and the console operators want to hear one another over the talkpath, you must enable conferencing and set the conference mode to Audio Linked ; otherwise each operator will only be able to hear the audio received from the radio, but not the other console operators. Advanced SIP Settings Select SIP in Advanced Mode to configure the advanced settings for the Session Initiation Protocol (SIP), as shown in Figure 25. For information about the basic settings, refer to SIP Basic Settings on page 44. Note The DRG implementation uses SIP for terminating two-party (unicast) sessions only. Figure 25. SIP configuration settings DRG200i Product Manual 59

68 The DRG200i also supports the transmission of audio over a unicast VoIP link established by a SIP session, such as those used by RediTALK-Flex consoles. In this case, you should the Remote IP Address setting of the conference DRG to on the VoIP/RTP page (see Remote IP Address on page 42). Additionally, to allow multiple consoles to communicate with each other, you should enable the Audio Linked conference mode (see Connecting Multiple Devices in a Conference on page 57). For further information about SIP, refer to Session Initiation Protocol (SIP) in the Technical Reference section on page 95. Advanced Settings Server The settings under this section configure a connection to a SIP server and are used to allow the DRG to connect to a telephony system such as a SIP-enabled PBX or VoIP server. These settings are all enabled when the SIP Server Enable is selected. SIP Server Enable allows the DRG200i to register with a SIP server. This is required if the DRG200i is interfacing with a phone system. If the DRG200i is connecting directly to another Omnitronics product, a SIP server is not required. The default is disabled. 60 Advanced Configuration Note When using a SIP server, the DRG200i may need to use a DNS server. If the DRG200i is using DHCP, the DNS server will be automatically configured. If the DRG200i has a static IP address, the DNS value will need to be configured. SIP Registrar Server is the IP address of the SIP server with which the DRG will register. This can be an IP address (e.g ), a fully-qualified domain name (e.g. somehost.example.com), or a SIP URI (e.g. myhost.example.com). The default is blank. For a list of compatible SIP Telephony Servers and Soft Phones, refer to Compatible SIP Servers and Devices on page 63. SIP Outgoing Proxy is the address of the server used for SIP registration. Some SIP service providers use a separate server for registration and making calls. The SIP service provider will provide the address details for your configuration. This can be either a numeric address or a fully-qualified domain name. SIP services generally work with DNS name resolution, so this address is most likely to be a fully-qualified domain name of the form host.org or host.net.au. The default is blank. SIP Server Password is the password that the DRG uses to register with the SIP server. Allowed value is a text string without any spaces. Default is blank. SIP Realm is a string displayed to users so they know which username and password to use this is part of the authentication process. This string should contain at least the name of the host performing the authentication, and it may also include a group of users allowed to access the server, such as registeredusers@omnitronics.com.au. When the DRG registers with the SIP server, it provides a username, realm, and password. This value is provided by the SIP service provider. Allowed value is a text string without any spaces. Default is blank.

69 Registration Expires is how often the DRG must reregister with the SIP server. Allowed value is 60 to 32000s. The default is 900s. Advanced Settings General Enable status sounds allows the DRG200i to play a distinctive sound when a SIP connection is established or disconnected. Push-to-talk is activated automatically while the audio is played. The delays for DTMF/SELCALL lead-in and lead-out are used to control the PTT lead-in and lead-out. The default value is disabled. The DRG200i can play the following status sounds: Connected connect.wav (4 short beeps) Disconnected disconnect.wav (single beep: 0.5s 524Hz tone) Connection in progress ringing.wav (ring tone) Connection failed failed.wav (busy tone) Disable changing transmit CODEC type option prevents the DRG200i from changing the codec type used to transmit audio when a SIP connection is received. The codec type is specified on the VoIP/RTP configuration page. If this option is not selected, the DRG200i may change the codec type used to transmit audio when a SIP connection is received. If this option is selected, the DRG200i will still accept and decode received RTP audio packets that use a different codec type. Disable non-standard RTP packets for SIP Connections option disables Omnitronics RTP extensions for third-party SIP connections. Select this option only when connecting to a third-party SIP device, such as a SIP phone, that does not support Omnitronics RTP extensions. Use alternate destination with NAT option is normally disabled but can be used to enable SIP to work across a router using NAT (see Network Address Translation (NAT) on page 90). Select this option to use the alternate SIP parameters when using SIP in conjunction with NAT, and when the translated ports and addresses are known (usually obtained from the router configuration). IP Address is the alternate IPv4 address of the DRG on the other side of the NAT. Receive RTP Port is the alternate RTP port of the DRG on the other side of the NAT. Receive SIP Port is the alternate SIP port of the DRG on the other side of the NAT. DRG200i Product Manual 61

70 Voice Activity Detection The DRG200i is a gateway between phone systems that do not provide the standard E&M control interface. To provide a mechanism to control radios that need PTT signal, the DRG200i can perform Voice Activity Detection (VAD) on the audio received from the network. The settings under the Voice Activity Detection (for SIP devices) include the following: PTT/Busy control mode determines how the DRG200i controls the local PTT (or Busy) and can be one of the following: Normal (controlled by remote device) (SIP) Connection Active (VAD) Voice Activity Detection This is the same functionality as provided by an RTP connection: remote busy status or CTCSS keying controls the local PTT/Busy output (this is the default setting). While a SIP connection is active, the local output is active. When the SIP connection is terminated, the output becomes inactive. This could be used with a full-duplex radio. When the DRG200i determines the remote device is sending voice data, the local PTT/Busy output is activated. If the remote device supports silence suppression (meaning that it will stop sending packets when it detects the operator is not talking), the DRG200i will use the presence of packets as part of its VAD algorithm. Use fixed threshold for VAD allows you to select a fixed threshold for detecting voice activity instead of using an adaptive threshold. You can select the fixed threshold from the drop-down list for the following parameter to adjust the sensitivity of the network Voice Activity Detection. If this option is deselected, the IPR110Plus will automatically adjust the sensitivity of the VAD. The default setting is disabled. Note The threshold sensivity for VAD only effects the detection of voice for data coming from the network and controlling the local Push-To-Talk output; and it does not effect the VAD algorithm used for audio input. Fixed VAD threshold sensitivity allows you to select a fixed threshold sensitivity for detecting voice activity. You can select one of the following settings: Receive Level Loudest Receive Level Loud Least sensitive: PTT requires high level of audio before PTT is activated. Select this option for environments with high levels of background noise. Less sensitive: PTT activation requires more voice signal form the remote SIP phone. Select this option if PTT is activated by background noise. 62 Advanced Configuration

71 Receive Level Quiet Receive Level Quietest Not as sensitive: PTT activation requires more voice signal from the remote SIP phone. Select this option for low-levels of background noise.

80 RTP receive total packets is the total number of RTP VoIP packets received by the DRG200i from remote devices. RTP receive valid packets the number of valid RTP packets received from the remote device. RTP receive invalid packets is the number of packets received that do not contain valid RTP formatting. If this number is very large, it may indicate that this port is being used by some other network protocol. RTP receive valid bytes is the total number of bytes received via RTP. RTP receive sequence errors indicates the number of packets that either were not received or which arrived out of order. If this value is large, it indicates that the network is experiencing packet loss or excessive network jitter. RTP receive packets too late indicates that a packet containing audio arrived at the DRG200i after it should have been played. If this value is large, it indicates excessive and changing network propagation delays. RTP receive STUN packets indicates the number of value STUN messages received. Some VoIP clients send STUN messages on the RTP port to help determine network configuration. RTP receive MULTICAST packets indicates whether a packet has been received from a multicast address. RTP transmit packets is the number of complete network (UDP) VoIP packets sent, but does not include other packets such as web server data or SNMP packets. RTP transmit bytes is the total number of data bytes sent, and includes the payload data, but it does not include the overhead due to Ethernet protocol. Current transmit bytes per second is an estimate of the current bandwidth usage for VoIP. This will display a non-zero value only if the DRG200i is currently transmitting audio information. Time since valid RTP packet is the time in milliseconds since the last RTP packet was received. RTCP receive total packets is the total number of RTCP packets received. RTCP receive valid packets is the number of valid RTCP packets received from the remote device. RTCP receive valid bytes is the total number of bytes received via RTCP. Time since valid RTCP packet is the time in milliseconds since the last RTCP packet was received. Source Name is the network name of other VoIP devices communicating with this particular DRG200i channel and is obtained from RTCP packets received from that device (e.g. IPE/Radio:2@ ). Location is the location or name configured in the remote VoIP device (e.g. DxAltus Radio Channel 1). 72 Diagnostics, Statistics, and Upgrading the Firmware

81 Firmware Information identifies the firmware, and the version of the firmware, that this DRG device is running. Source IP Address is the source IP address for this audio source, such as Source UDP Port is the UDP Port for this audio source, such as Received packets is the number of VoIP data packets received from the remote device. Duplicate packets is the number of packets that have been detected containing exactly the same data (network errors). Misordered packets is the number of packets that have arrived out of order, usually due to network delays. Packets arrived too late is the number of packets that have arrived after the point where they should have been played (network errors due to high latency). Current playout delay is how much audio (in milliseconds) the DRG200i device is currently holding in its jitter buffer. Current Busy State is the current state of the Busy (Mute) input. Current PTT State is the current state of the remote audio source requested for the local DRG200i PTT output. This will appear if the remote site currently has an active busy signal from a connected radio.

You can disable or delete the patch group on this device. A disabled patch group is indicated by an Enable button; and an enabled patch group is indicated by a Disable button. Note If you delete a patch group, you must manually delete it on the other devices in the patch group; otherwise, DX-Altus will receive different reports about the patch group resulting in oscillations. Updating the Firmware Omnitronics may release new versions of the DRG firmware to add additional features or to resolve issues. You can update the firmware from the Firmware Upgrade page, as shown in Figure 35. This page is accessible only under the Administrator account. Figure 35. Upgrading the firmware 76 Diagnostics, Statistics, and Upgrading the Firmware

85 Before updating the firmware, it is recommended that you back up the configuration settings (see Backing up and Restoring the Configuration on page 34). You can check the version of the existing firmware by viewing the System Status page (see Viewing the System Status on page 29). When updating the firmware, you will need to update the firmware for both channels, one at a time. Important The DRG firmware determines the type of digital-radio interface supported. You need to take care when updating the firmware to ensure you update from a compatible version, and you select the correct firmware for the type of radio interface check the Release notes to ensure you do not require an intermediate update first (otherwise you may lose your configuration during the update). To update the firmware in the device 1 Login to Channel A of the device. 2 Click Browse to locate the firmware file on your computer. The firmware file is identified with a.bin.gz extension. Its full path and filename will appear in the Select file text box once you select the file. Important Do not use decompression software to decompress the.bin.gz file: the firmware update process uses the compressed binary image to save space in flash memory. 3 Click Upgrade to commence the update process. While the firmware update is in progress, a progress indicator will keep you informed of the progress. Warning! Do not remove power to the DRG200i while it is updating; otherwise it may cause damage to the hardware or corrupt the firmware. DRG200i Product Manual 77

86 Once the firmware is transferred, the DRG200i writes it to Flash memory. After writing the firmware to Flash, the DRG200i will then verify the integrity of the firmware. Once the firmware verification is completed, the Verified OK message will appear on the page indicating that the firmware is successfully loaded into Flash memory. 78 Diagnostics, Statistics, and Upgrading the Firmware

87 Important If the device fails to update, do not remove power: try repeating the firmware update process again. 4 Click Restart to restart the DRG200i. Once the DRG200i has restarted, you may need to login again if you want to check or change any of the configuration settings. Note If the configuration settings in DRG200i have reset to the factory default settings after updating the firmware, you can restore the configuration from a backup file. It is recommended that you clear your browser s cache to ensure all the latest JavaScript and image files are downloaded from the device. 5 Repeat steps 1 to 4 above to update the firmware for Channel B. The firmware update for both channels is now complete. DRG200i Product Manual 79

89 Serial Monitor This section discusses how to use the built-in Serial Monitor via the USB connection to perform basic configuration of the device, and includes the following topics: Overview Serial Communications Setup on page 82 Using the Serial Monitor on page 83 Resetting to Factory Default Settings on page 84 Overview The Serial Monitor is intended only for technicians or Omnitronics support engineers to assist in diagnosing and troubleshooting problems. You can also use it to configure the basic network settings of the DRG to establish network connectivity. Once network connectivity is established, you can then login to the configuration interface with your web browser to configure the DRG200i channels (you should use the built-in configuration interface to configure the DRG.) Before using the DRG200i device for the first time, you will need to configure the basic network settings to suit your particular environment. The easiest way to do this is to use the Serial Monitor with serial communications software such as TeraTerm this popular serial communications software is freely downloadable from the Internet; however, you can use whatever serial communications software you like. The following section discusses how to set up TeraTerm to communicate with the Serial Monitor (see Serial Communications Setup on page 82). DRG200i Product Manual 81

90 Serial Communications Setup This section describes how to set up TeraTerm for use with the built-in Serial Monitor. The same steps should apply to other serial software. The Serial Monitor uses the USB port on the front of the device to communicate with serial communications software, such as TeraTerm. You should note that the USB port will appear as two virtual COM ports on a Windows computer (e.g., COM1 for Channel A and COM2 for Channel B). Select the port you want to use depending on which channel you want to monitor. To connect to the Serial Monitor 1 On the Serial port setup dialog, select the port and then set the values as follows: Baud rate: 19200, Data: 8, Parity: None, Stop: 1 bit, and Flow control: None. 2 Click OK to close the dialog. 3 Press Enter on the keyboard. You should now be connected to the Serial Monitor, and you should see the command prompt. The prompt you see depends on the firmware for the DRG200i-DMR-AIS firmware, the prompt is dmr-ais(a)$ (for channel A) and dmrais(b)$ (for channel B) as shown in the screenshot below. 82 Serial Monitor

91 Using the Serial Monitor The Serial Monitor is used to perform basic configuration and diagnostics for a particular channel of the DRG200i. You can set the IP address, gateway address, and subnet mask to establish network connectivity with the device. You can also restore the DRG200i to factory-default settings (see Resetting to Factory Default Settings on page 84). All of the configuration functions provided by the Serial Monitor are also available via the built-in configuration interface. Using the Serial Monitor, you can issue commands to: Display the current configuration Change the basic network settings Reset to factory-default settings Send a network ping to test the network connectivity Perform diagnostic troubleshooting Before you can use the Serial Monitor, you should set up your serial communications software (see Serial Communications Setup on page 82). You can then enter commands at the Serial Monitor command prompt by typing the command name followed by the command argument(s), and ending the command by pressing the Enter key some commands allow you to specify a command argument(s) to provide additional information for the command. The common commands used for basic configuration are listed below. Command aconfig defaults set ipaddress set netmask set gateway set dhcp ping reset Description Application Configuration command displays the current application configuration settings. Usage: aconfig Resets all configuration values back to factor default settings. Usage: defaults Sets the IP address. The format of the address is n.n.n.n where (n) can be any number between 0 and 255. Note: this will have no effect if the device is configured to use DHCP to automatically determine its IP address. Usage: set ipaddress <address> Sets the subnet mask. Format is the same as ip address. Usage: set netmask <netmask> Sets the gateway address. Format is the same as ip address. Usage: set gateway <address> Enables or disabled dhcp mode. In DHCP mode, the IP address of the device is automatically allocated by a server. Usage: set dhcp 0 to disable DHCP or set dhcp 1 to enable DHCP. Sends a special echo message to another machine on the network to test communications. Usage: ping <new address> Causes the device to reset. Usage: reset DRG200i Product Manual 83

92 To see a complete list of the available commands, enter help at the command prompt, as in the following example: dmr-ais(a)$ help <Enter> The Serial Monitor provides many commands in addition to the commands listed in the table. However, the additional commands are intended only for device testing and debugging these are not intended for initial configuration or for use in a live radio network. Important If you set the DRG200i device on a different IP network or subnet to the computer used to access it, you may not be able to access the configuration interface due to incompatible network settings. Resetting to Factory Default Settings You can use the Serial Monitor to restore the DRG200i to its factory-default settings by issuing the defaults command, followed by the reset command. Note You may lose network connectivity with the configuration interface after resetting your device to factory-default settings. In this case, you can use the Serial Monitor to set the basic network settings to match your network. If you do not want to use the Serial Monitor, you can reset the DRG200i using the Reset to Defaults button on the back of the device. This button is recessed to prevent accidental reset of the device use the end of a paper clip or some other similar object to press and hold the Reset to Defaults button while applying power. Use the following procedure to reset the device. To reset the device to default settings 1 Remove power to the device. 2 Using a paper-clip, depress and hold the Reset to Defaults button while applying power to the device. 3 Wait until the Run indicator on the front panel starts to flash quickly, and then release the Reset to Defaults button. Note This could take up to 30 seconds especially when the network cable is disconnected. 4 Remove power to the device. 5 Wait for several seconds, and then reapply power to the device.

95 Technical Reference This section provides technical details on the protocols used by the DRG product family, and includes the following topics: IP Addressing via the Internet and Local Area Networks VoIP Functionality on page 93 Simple Network Management Protocol (SNMP) on page 97 Specifications on page 101 Notice of Compliance on page 103 IP Addressing via the Internet and Local Area Networks This section discusses some of the more complicated issues that may occur when using the DRG200i products in certain configurations. IP Addressing The DRG product family provides full support for IPv4; however, as at the time of publication, it does not support IPv6. Therefore, this section discusses IP addressing with respect to IPv4. All devices connected to the Internet or using IP for communication have an IP address. An IPv4 address consists of 32 bits expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. An example of an IPv4 address is The IPv4 address consists of two parts: the network address and the host address. The subnet mask determines what part of the IPv4 address is used to identify the subnet on which a device is located. A valid IPv4 subnet mask consists of 32 bits: a sequence of ones (1) followed by a block of zeros (0), expressed dot-decimal notation. The sequence of ones (1) designates that part as the network address (subnet) and the block of zeros (0) designates that part as the host identifier. Not all IP addresses are created equal, however, and certain ranges of addresses have specific functions. Some addresses are allocated from the private address space used for private networks while others are allocated for multicasting. Currently, three classes of IP addresses are commonly used: Class A (the largest) is identified by the first octet, which ranges from 1 to 126. Class B s identified by the first two octets, the first of which ranges from 128 to 191. DRG200i Product Manual 87

96 Class C (the smallest) is identified by the first three octets, the first of which ranges from 192 to 223. The following lists the different classes and address range of an IP Address: IP Address Class Range of First Octect Network Identity Host Identity Subnet Mask A a b.c.d B a.b c.d C a.b.c d Some first-octet values have special meanings: First octet 127 represents the local computer, regardless of what network it is really in. This is mainly used for local loopback testing. First octet 224 and above are reserved for special purposes such as multicasting. Octets 0 and 255 are not acceptable values in some situations, but 0 can be used as the second and/or third octet (e.g ). Another type of private networking uses the link-local address range (in IPv4, the block x.x, which is also shown as /16, is reserved for this purpose). This address range allows a network device to auto-configure its IP address when Dynamic Host Configuration Protocol (DHCP) services are not available. If a host on an ethernet network cannot obtain a network address via DHCP, an address from to may be assigned pseudo randomly. The IP address space is controlled by the Internet Assigned Numbers Authority (IANA). Multicast Addressing Multicast addressing or multicasting is a method of implementing efficient one-tomany communications. The originating device sends a single packet and the network infrastructure will deliver the packet to all the devices that are listening to the multicast address. Any device that wishes to receive packets sent to a particular multicast address will need to join the multicast group. The protocol used to manage this process is the Internet Group Management Protocol (IGMP). The actual routing of multicast packets efficiently is complicated and is managed by the routers and switches that form the network infrastructure; this complexity is not visible to the end devices that simply have to join the group. The range of addresses to is reserved for multicast addresses: using any address within this range will automatically put the DRG200i into multicast mode. Note Multicast addresses in the range of to are reserved and should not be used. 88 Technical Reference

97 IP Addresses in the range of to are multicast addresses, and are used for Internet-wide addressing. Using any address from within this range will automatically put the DRG200i into multicast mode. You should use these addresses for communicating over a WAN or over the Internet. Multicast Addresses in the range to are used for local addressing and should be used for multicast configurations where all DRG200i devices are on the same LAN, or are all configured on the same IP subnet. Using multicast addressing, a single data packet is routed to multiple destinations; the network will only duplicate the packet if it needs to go to several different locations. For multicast addressing to work, all the network routers in the network must support multicast addressing and have multicasting enabled in their configurations. If your network does not support multicasting, the conference modes provide an alternate solution (see VoIP Conference Mode on page 56). Audio received at any DRG200i in the multicast group is transmitted once and received by all the other DRG200i devices in the group. Effectively all the radios or consoles are linked together. If any device fails, only that device is affected. All the devices are configured to use a single multicast address as the remote address for their VoIP link. Note Many routers on the Internet, and most ADSL/DSL modems, do not support multicasting. Domain Name System (DNS) When accessing a web site or computer on the Internet, the address is usually expressed as a hostname or a domain name like These host names are actually converted into an IP address using the Domain Name System (DNS). A computer will communicate with a DNS server that will then provide the actual numeric IP address that corresponds to the hostname. A hostname consists of two or more labels; the rightmost label is the top-level domain and will be something like com or au. Each label to the left specified a sub domain of higher domain to the right. Omnitronics DRG products include the support for sending requests to DNS servers, and hence converting host names into numeric IP addresses. Dynamic Addressing Using a DHCP Server Most networks allocate IP addresses to computers and devices on the network using DHCP (Dynamic Host Configuration Protocol). The network provides a DHCP server that automatically assigns an IP address to each network device. DHCP is also widely used for dial-up and broadband Interconnection. DRG200i Product Manual 89

98 The DHCP assigns the IP address, IP subnet mask and default gateway. DHCP servers generally provide addresses with a lease on a particular address for a certain time. As long as the device is leased, and a particular address is renewed, the address will remain allocated to that device. If the device does not renew the lease, the address may be allocated to some other device or computer. If a device that is configured for DHCP cannot contact a DHCP server on start-up, it will not have a valid IP address. In this case a device can default to using an address in the range Network Address Translation (NAT) Figure 36 illustrates the process of Network Address Translation (NAT). This involves over-writing the source and destination addresses of IP packets as they pass through an ADSL modem or router. Systems using NAT do so in order to enable multiple hosts on a private network to access the Internet using a single public IP address. As well as over-writing the IP addresses, sometimes the IP port number can also be changed this is sometimes referred to as port forwarding. Figure 36. Using Network Address Translation (NAT) Since there may be multiple computers behind a router that is configured to use NAT or port forwarding, it is necessary to configure the router to know the IP address of the DRG200i device to which a particular port should be forwarded. So for a VoIP link to work through a router that is performing Network Address Translation, additional configuration is required both at the DRG device and at the router. SIP Network Address Translation can be even more problematic. Part of the SIP call set up is to negotiate which ports to use for sending the RTP/RTCP data. Because these ports are dynamic it is not possible to set up the router in advance for port forwarding. Many ADSL routers include SIP Application Level Gateways (ALG). An ALG is a software component that runs on the ADSL router that understands a particular protocol and allows that protocol to work despite the firewall and NAT. The SIP ALG will re-write parts of the SIP translation with the correct information and set up the associated port forwarding settings automatically. 90 Technical Reference

99 Dynamic Domain Name System (Dynamic DNS) Dynamic DNS is a system for allowing an internet domain name to be assigned to a non-static public IP address. This makes it possible to remotely establish connections to network devices without the need of tracking their changing public IP addresses. Most internet service providers employ a technique of allocating IP addresses dynamically on demand unless clients desire a fixed IP address. As fixed IP addresses come at a premium, most internet users make do with dynamic IP addressing. Network devices that are hosting services behind routers with dynamically changing IP addresses will thus only be reachable by means of DNS lookup. For this to work, however, it is important that references to IP addresses are kept up to date. The onus of keeping the DNS server(s) up to date rests on either the router or at least one network device behind the router. Implementation The Dynamic DNS feature can be enabled on any DRG200i. If this feature is enabled, the DRG200i will perform all dynamic DNS related operations; and it will be responsible for tracking changes in the public IP address by which the device will be reachable across the internet. As an DRG200i device will typically reside on the private side of a company's network (behind the public router), it will have a private IP address. In order for an DRG200i device to connect to a remote DRG200i, it will need to know the public IP address of the router at the remote end. Furthermore, if the public IP address of the router changes, the Dynamic DNS feature will update its configured Dynamic DNS server. This involves an HTTP request to associate its fully qualified domain name to the new public IP address. Any subsequent name resolution requests should then resolve to the latest public IP address. The DRG200i configuration allows for all remote ends to refer to fully qualified domain names. This applies to the VoIP remote destination, conferenced remote destinations, and serial pass-through remote destination addresses. An additional feature of the Dynamic DNS is to perform periodic name resolution of these destination addresses provided they do not contain a raw IP address. If any of the configured remote devices experience a change in public IP address, the local DRG200i will perform the required housekeeping to re-establish the RTP, or the conferenced or pass-through communications. Additionally, any SIP conversation can also benefit by optionally forwarding the public IP address of the device to the remote side during SIP call establishment. Compatibility The Dynamic DNS client is designed to be compatible with the DynDNS API as both DynDNS.com and No-IP adhere to this API standard. Minor modifications were made to the client to accommodate ChangeIP.com. The client may well be compatible with other Dynamic DNS host services if they adhere the the DynDNS API but this cannot be confirmed. The best approach will be to try your preferred dynamic DNS host service to see if the DRG200i is compatible with it. DRG200i Product Manual 91

100 Configuration Figure 37 shows the different aspects of the dynamic DNS configuration. The Dynamic DNS feature will not work unless at least one of the DNS server fields (A) points to an actual DNS server that is reachable by the device it affects the ability of the device to perform domain name resolution. A value of indicates that this setting is not in use. Ideally these DNS server fields should point to the IP addresses of the DNS servers provided by your ISP used to access the internet. Figure 37. Dynamic DNS configuration The Public IP Service (C) should point to the URL of web services that return the public IP address of the requester. This public IP address should be available as a text string within the response in the IPv4 format as described in IP Address (see IP Addressing on page 87). The following are examples of public IP servers: It is best to use a public IP service with a concise text response. Dynamic DNS updates require at least one of these fields to point to an actual public IP service. It is best to have both configured for redundancy. The other Dynamic DNS settings (D) are required by the built-in dynamic DNS update client to keep the Dynamic DNS host informed about changes in the public IP address of the Device Domain Name. If any of these settings is left blank (i.e. not configured), dynamic DNS updates will not occur. Examples of Dynamic DNS Host Update domain names are: DynDNS.com uses members.dyndns.com no-ip uses dynupdate.no-ip.com ChangeIP.com uses nic.changeip.com (A) DNS Servers At least one DNS server is required (B) Syslog host address Required to log dynamic DNS activity (C) Public IP Service Returns the public IP address of the requester (D) Dynamic DNS Host Required to update the dynamic DNS host The above examples are by no means endorsed by Omnitronics; however the product was tested with these and known to work perfectly at the time of publication of this document. The configured Device Domain Name must be registered with the authority configured in the Dynamic DNS Host Domain Name field. 92 Technical Reference
